That did the trick. The stack trace allowed me to track down the
cause of the error. Because Objective-C++ does not have a concept
of class static variables I had an NSArray defined in an anonymous
namespace in the implementation module that was initializing its
contents. I changed the code so the array is initially set to nil
in the anonymous namespace, and then assign it to an NSArray
instance the init method of the class using the array if the array
had not been initialize.
I'm guessing the code you just wrote is not thread-safe - if two
threads are simultaneously the first to call -init then things might
go wrong. If you need thread-safe initialization, the +initialize or
+load methods are usually better.
